On the Analysis of Secrecy Outage Probability Using Average Channel Capacity
Sakarya University Journal of Science, 2020 In this article, we analyze the outage probability of physically secure wireless signal transmission in fading envi-ronments where both primary and eavesdropper channels are subject to generalized fading. We propose a novel approach using the average channel capacity of the primary channel and that of the eavesdropper channel to the outage probability ...

Outage Constrained Robust Secure Transmission for MISO Wiretap Channels [PDF]
, 2013 In this paper we consider the robust secure beamformer design for MISO wiretap channels. Assume that the eavesdroppers' channels are only partially available at the transmitter, we seek to maximize the secrecy rate under the transmit power and secrecy ...

Journal of Field Robotics, EarlyView.ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...
